I ordered medium, which is my true size, and I absolutely loved these. Geo lace is my favorite material of the whole collection. a couple of weeks after I bought them, the geo lace fabric came apart from the elastic waist band. So disappointing because they feel so nice and expensive. I am split on if I will ever buy a pair again because I don't want to spend so much money on underwear that will fall apart.
Definitely do not buy to wear under heavy jeans/pants and be sure to hand wash them!

Trust me girls, this is what every modern woman who can't necessarily afford to stuff her lingerie drawer with ERES or La Perla has been waiting for. The fabric feels amazing, the fit is great and I love the geometric lace.. It's so modern and sexy. I can't wait for the matching demi-bra she's wearing!
